I think in the Star Trek Universe, most humanoid species are compatible. Some more than others, some less. I think real difficulties occur between humanoid and non-humanoid species (like the Horta, Species 8472, and other life-forms that aren't even remotely humanoid in shape or genetic structure (say, non carbon-based).
Dude, you're speaking about a subject you obviously know absolutely nothing about. That is never a good idea. If you have no problem with impossible creatures on Star Trek, that's fine but don't try to argue that they are actually believable. Hybrids are flat-out impossible outside of being genetically engineered and grown in a lab. That is not an opinion.
